Alastor x Female reader

So,this is an AU where you are Charlie's big sister.You are a demon,or maybe not,no one knows😉.Okay,maybe someone does🤐
h/c =hair color
e/c =eye color
n/n =nick name
and so it goes on with all that stuff,i am sure you all know what this stuff means.
Well,ahem,you are known as Overlord or as "the bloody demon",you are really powerful and always smile.You have a cane or whatever,its something like Alastor has but it isnt a microphone,more like a cepter or something similar to that and you always carry it with you around.
But your real powers will be a secret for now,you can teleport tho,thats the only thing i will tell for now.
